j i trolling the depth of the rear end of the boat and also capable of functioning, as brakes.

A still further very important object of the invention resides in the provision of a boat of this nature which is comparatively simple in its construction, inexpensive to manufacture, strong and durable, thoroughly eflicient H and reliable in use, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and 09 claimed.

In the drawing:

Figure 1 isa top plan view of the boat embodying the features of my invention,

Figure 2 is a side elevation thereof,

Figure ,3 is a front elevation thereof, and

Figure 4 is a fragmentary perspective View showing the rear portion thereof.

Referring to the drawingin detailit will be seen that theletterA denotes generally the body of the boat which has its front end 5 of the sleigh style front so as to cause the boat to plane or skim over the water and to draw only a few inches of water when at full speed. The bottom of the body A is stepped upwardlyand rearwardlyas indicated at 6 so as to cause the minimum drag resistance of the rear of the boat body.

i A housing H is built above the body A eX- tending from approximately its rear end thereof to a distance rearwardly of the front edge and this housing has its forward end tapering forwardly with a motor, not shown, housed therein for operating a propeller 7.

A plurality of windows 8 are providedin the sides of the housing. A pair offinsf) project horizontally and outwardly from the rear end of the housing H and have elevators 1O hingedly connected on their rear edges.

. A rudder 11 is hingedly connected on the rear end of the housing and on therear edge of a vertical fin l2 rising from the rear end of the housing.

A wing 14 extends transversely across the forward portion of the housing and has mounted in the entrance edge thereof a pluf rality of motors 15 for operating propellers l6. Acockpit 17 is formed in the center of the wing and all the five motors are adapted to becontrolled therefrom and the elevators and rudders are also adapted to be controlled therefrom. i

The elevators function to even up the balanoe ofthe boat and to care for added weight and also may be used as brakes. The wing carrying the four motors is adapted to lift the weight of the motors and, therefore, makes the front of the boat comparatively light and assuming a planing effect. The. air rudderll permits of sharp turns at high speed. 89 It will be noted that there is nothing below the bottom of the boat and therefore it is possible to beach the same without injury to the boat. Only one man is necessary to control the whole boat and the housing may be sufficiently large to house a comparatively great number of passengers using a seating plan similar to the ordinary motor bus or railroad coach and preferably being double decked. p

This boat may be used for excursion purposes or as a speed boat. It will be understood that this aero-speed boat is not an aeroplane and will under no conditions leave the water, the wings being simply to carry the four motors and have them in the line so that the power will be evenly distributed throughout the boat. It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. I The present embodiment of the invention has been disclosed in considerable detail 5 merely for the purposes of exemplification since 111 actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

m It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or 15 without sacrificing any of its advantages.

' Having thusdescribed my invention, what I claim as new is: a

An aero-speed boat comprising an elongated hull of a type adapted to skim along '9 the surface of the water, a cabin extending longitudinally of the hull and converging at its forward end to provide a forwardly tapered motor housing spaced rearwardly of the bow of the hull and upwardly above the as deck of the latter, a motor-driven air proller associated with said motor housing, a ifting wing mounted transversely of the forward portion of the saidcabin and having a cockpit formed in the center thereof, a pluso rslityof air-propellers mounted on the said wing adjacent the forward edge thereof, said wing being of such lifting capacity as to compensate for the weight of the propeller units mounted thereon without causing the hull to 35 rise entirelyfrom the'water, elevator means on the rear end of the cabin, and air rudder means also at the rear end of the cabin.

In testimony whereof I affix my signature.

PAUL KENNETH DUDLEY.
